![]() ![]() ![]() Stock 1 typically has the least variation. Useful in visualizing most of the spread of variation.1 st Quartile and 3 rd Quartile: The lower end of the box is the 1st quartile, and the upper end is the 3rd quartile.Median: The blue horizontal line indicates the median of the group.Middle values: The box indicates the range in which the middle 50% of all data lies.When the data is in metric scale levels such as age, temperature, etc.To read the median, interquartile range, and outliers in the data set.Box plots help to display various parameters at a glance.To compare the process changes before and after the improvements.Box plots compare multiple data sets from independent sources that may have some relationship.It shows how the data scattered within those ranges will help for effective decision-making. It is also called a box-and-whisker plot or “five number summary.” In other words, quartiles, the median, and the highest and lowest values. Graphically it shows the variation between multiple variables and the variations within the ranges. These lines indicated the variability outside the upper quartiles and lower quartiles.īox plots are very effective and easy to read. It has the name box and whisker because the lines extend vertically from the boxes. Both the upper and the lower quartiles are displayed as horizontal lines on both sides of the rectangle. And there is a vertical line that shows the median value. Rectangles are drawn to show the second and the third quartiles. Box plots show the max, min, median, interquartile range Q1, Q3, and outlier. Different graphical tools, such as Run charts, Scatter diagrams, Histograms, and Pareto Chart depict different data features such as trend, frequency, dispersion, and shape of the distribution. Box plot, a.k.a Box and Whisker plot, is a pictorial representation of continuous data. It is an effective way to visualize data patterns and provides key insights into the data. Graphical analysis is one of the best ways to analyze the problems in Six Sigma projects. In other words, Box plots are used in statistics to graphically display various parameters at a glance. It also makes comparisons quickly and easily. Box plots are graphical tools that let you easily visually compare variations between the data sets evaluated. ![]()
